forms throughout the storage user interface. This general choice allows you to avoid difficult

decimal representations of storage size (for example, if you know that most of your storage is

measured in gigabytes, terabytes, or other more familiar representations).

Additionally, the Welcome to Storage Configuration Interface page lists systems that you are

authorized to access, but currently are unable to administer because of a problem. Examples of

problems:

• A computer is unreachable via the network.

• A computer has been re-imaged and the luci server admin must re-authenticate with the

ricci agent on the computer.

A reason for the trouble is displayed if the storage user interface can determine it.

Only those computers that the user is privileged to administer is shown in the main navigation

table. If you have no permissions on any computers, a message is displayed.

After you select a computer to administer, a general properties page is displayed for the com-

puter. This page is divided into three sections:

• Hard Drives

• Partitions

• Volume Groups

Each section is set up as an expandable tree, with links to property sheets for specific devices,

partitions, and storage entities.

Configure the storage for your cluster to suit your cluster requirements. If you are configuring

Red Hat GFS, configure clustered logical volumes first, using CLVM. For more information

about CLVM and GFS refer to Red Hat documentation for those products.
